What are the fundamental laws of Boolean algebra?

Fundamental Boolean algebra laws include: Identity (A+0=A, A*1=A), Null (A+1=1, A*0=0), Idempotent (A+A=A, A*A=A), Complement (A+A'=1, A*A'=0), Commutative (A+B=B+A), Associative ((A+B)+C=A+(B+C)), Distributive (A*(B+C)=A*B+A*C), Absorption (A+A*B=A), and De Morgan's theorems ((A*B)'=A'+B', (A+B)'=A'*B'). These laws are essential for simplifying Boolean expressions and optimizing digital circuits.
